I was going to go for the 2.05" I really wanted them, but Futral and a few other reputable names said that it may work, but a big IF. This along with the fact that 2.02"s can be done on stock seats I decided not to push my luck.
I'm also decided to step up to the F14 which is even less friendly towards the 2.05" valves.

Was your car a PITA to tune? Do you have cats?
Thanks!
I'm thinking about stepping up to this cam also, but I haven't heard of anyone using it in an A4 yet. I have GTP stg 2 heads and 224/224 .581" 114lsa cam right now, but wanting to go a little bigger. Everything I've read, it's been recommended to go with the F13 on a 112 +2 or 112 +0 if you weren't afraid to shift pretty high. What do you guys think would be ideal for an AUTO, and what should I have my stall/re-stalled to. It's a vig 2800 2.5str, but stalls closer to 32-3300.

(which is the range of the F14) he told me that the F13 112+2 is better for 6spd cars and +4 was better for auto's..actually let me correct myself 114 was better for auto's...he told me why but i forgot but if you talk with him, he'll let you know...thats my advice...just from talking with him i could tell he knew what the hell he was talking about...no hesitation, no "if's, or's, i dont know's" he answered me as soon as i asked the questions...good guy and really knowledgeable...
